Noah Goldstein 6dcbb7d95d x86: Shrink code size of memchr-avx2.S
This is not meant as a performance optimization. The previous code was
far to liberal in aligning targets and wasted code size unnecissarily.

The total code size saving is: 59 bytes

There are no major changes in the benchmarks.
Geometric Mean of all benchmarks New / Old: 0.967

Full xcheck passes on x86_64.
